Simsima for Japan FAQ
Does Simsima offer unlimited data eSIM for Japan?
Simsima does not provide a truly unlimited data eSIM for Japan. The plans labeled “Unlimited” are fixed‑data plans that allow 3 GB of high‑speed data per day; after that amount is used, the speed drops to 1000 kbps.
If a larger data allocation is desirable, Simsima offers fixed data plans such as the Japan 100GB 180‑day bundle and the Japan 50GB 30‑day bundle, both granting high‑speed data for the stated period. These options can be more cost effective for travelers who need a substantial amount of data but do not require unlimited usage.
Does Simsima offer Japan eSIM with phone number and SMS?
Simsima does not provide a phone number or SMS capability on its Japan eSIM plans; only data‑only plans are available. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging, but they should check that these services are accessible in Japan before purchasing.
How many data plans does Simsima offer for Japan?
Simsima provides 14 single‑country plans and 21 multi‑country plans for use in Japan. The available plans span a price range from roughly $1.50 to $178.48, with data limits that vary from 100 MB up to 100 GB.
